FIELD OF THE INVENTION

[0001] The present invention relates to opener, and particularly to ahigh torsion electromotive opener with enhanced power supply ability soas to provide high torque in operation

BACKGROUND OF THE INVENTION

[0002] The prior art electric tool uses batteries or wired power supplyfor supplying power. To be portable easily, batteries are suitable powersource for tools needing small torsion. However, batteries cannotprovide a larger current for generating a large torsion, especially intransient charging and discharge current. This is because batteriesgenerate power by chemical reaction. Moreover, the batteries storefinite charges. In reverse direction of an opener, a larger power isnecessary, however, batteries cannot provide such a larger current andthus the lifetime of the batteries is affected. Moreover, chemicalreaction will deteriorates the batteries. After using for a longer time,the batteries cannot saturate and thus cannot be used for a long time.Moreover, batteries need longer charge time. This induces inconvenientin use of the tool. Moreover, in general, the prior art tool does notequip with lamp for illumination and thus it is inconvenient when it isused in dark.

SUMMARY OF THE INVENTION

[0003] Accordingly, the primary object of the present invention is toprovide a high torsion electromotive opener comprising a casing, anelectrical control unit, a power supply and a lamp. The electricalcontrol unit is formed by a motor and a connecting unit. The motorreceives power from the power supply to drive the connecting unit torotate. The power supply includes at least one battery, an electric duallayer capacitor and a charge seat which are installed in predeterminedpositions within the casing. The batteries are connected to the electricdual layer capacitor in parallel and the charge seat is conductive tothe batteries. The charging and discharging of the electric dual layercapacitor is physical reaction and thus current flow is not limited. Theelectric dual layer capacitor is charged or discharged transiently. Whenthe power supply drives the electrical control unit to rotate, theelectric dual layer capacitor will charge the electrical control unittransiently so as to have a large torsion.

[0004] The various objects and advantages of the present invention willbe more readily understood from the following detailed description whenread in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE INVENTION

[0008] In order that those skilled in the art can further understand thepresent invention, a description will be described in the following indetails. However, these descriptions and the appended drawings are onlyused to cause those skilled in the art to understand the objects,features, and characteristics of the present invention, but not to beused to confine the scope and spirit of the present invention defined inthe appended claims.

[0009] With reference to FIGS. 1 to 3, the high torsion electromotiveopener of the present invention is illustrated. The high torsionelectromotive tool includes a casing 10, an electrical control unit 20,a power supply 30 and a lamp 40.

[0010] The casing 10 is formed by two half-casings. A long groove 11 isinstalled at a head end of the casing 10 for receiving the electricalcontrol unit 20. Another end of the casing 10 is formed with threereceiving grooves 12, 13, and 14 and two lamp grooves 15 and 16. Thethree receiving grooves 12, 13 and 14 serve for receiving the powersupply 30. The lamp groove 15 and 16 serves for receiving the lamp 40and an indicator light 50. An openable rear cover 17 can be formed on alower edge of the casing 10. An inserting hole 171 communicating to thethird receiving groove 14 is formed on the rear cover 17.

[0011] The electrical control unit 20 is formed by a motor 21 and aconnecting unit 22. The motor 21 receives power from the power supply 30to drive the connecting unit 22 to rotate. One end of the connectingunit 22 protrudes from the casing 10 for mounting an opener (not shown).An electric control switch 62 is installed at a connection of the handleand head of the casing 10 so as to control the rotation directions ofthe electrical control unit 20.

[0012] The power supply 30 includes a plurality of batteries 31, anelectric dual layer capacitor 32 and a charge seat 33. The batteries 31are installed in the first receiving groove 12 The electric dual layercapacitor 32 is installed in the second receiving groove 13. The chargeseat 33 is installed in the third receiving groove 14. The batteries 31are connected to the electric dual layer capacitor 32 in parallel. Thecharge seat 33 is conductive to the batteries 31. The charging anddischarging of the electric dual layer capacitor 32 are physicalreaction without any chemical reaction. Thereby, the current flow is notlimited. Thereby, the electric dual layer capacitor 32 can be charged ordischarged transiently. Thereby, when the power supply 30 drive theelectrical control unit 20 to rotate, the electric dual layer capacitor32 will charge the electrical control unit 20 transiently so as to havea large torsion.

[0013] The lamp 40 is high illumination LEDs and is mounted in the firstlamp groove 15. The lamp is controlled by a driving switch 61 on thecasing 10 so as to generate light for illumination. The indicator light50 is installed in the second lamp groove 16 of the casing 10 so as toindicate the charging condition of the charge seat 33.

[0014] Thereby, by above components, the efficiency of the electromotiveopener can be improved and power supply is increased. Thereby,efficiency of charging and discharging can be increased.

[0015] The details of the present invention will be further describedherein. When the power supply 30 is connected to an external device andsupplies power to the device, one end (not shown) of the externalcharger inserts into a receiving hole 171 so as to conduct to the chargeseat 33. Then charges will be stored in the dielectric batteries 31 andelectric dual layer capacitor 32 at the same time. Since the electricdual layer capacitor 32 can charge and discharge large currenttransiently, it can saturate at a short time period. Although thebatteries 31 do not saturate, if the user desires to use it immediately.The tool can be used by the power from the electric dual layer capacitor32. Since the current charge and discharge are physical reaction insteadof chemical reaction, the charge and discharge time period is long andthus the lifetime of the device is also long.

[0016] Moreover, when the present invention is used in a dark area, itis only necessary to open the driving switch 61 for controlling the lamp40, and then the lamp 40 will light up. In the present invention, superlight LEDs are used, which has a power consumption of only 20 mAh withan illumination of over 800 mcd and the lifetime can be as long as100,000 hours and thus it is more useful than the conventional bulbs.

[0017] The electric dual layer capacitor 32 (EDLC) is compared with thebatteries. In general, when the batteries are charged, the current islimited based on the Farady law (with the chemical reaction). Therefore,the transient charge and discharge are limited and the thus the currentis also limited. Since the charge and discharge of the current has nochemical reaction, it can generate a larger current. Since the chargeand discharge of the current has no chemical reaction, the lifetime isprolonged and times for charge and discharge of the current may achievea value of hundred thousands (the prior art battery is only 300 to 2000times). Even the EDLC shorted, the present invention can be used. Ingeneral, EDLC has the advantages of high power, high energy and compactsize and is made of material matching the requirement of environmentprotection. Thus it can provide a tool with such property.

[0018] In the present invention, super light LEDs are used to replacethe conventional tungsten light. The super light LEDs only consume acurrent of 20 mAh with an illumination of 8000 mcd and lifetime of100,000 hours.

[0019] The present invention is thus described, it will be obvious thatthe same may be varied in many ways. Such variations are not to beregarded as a departure from the spirit and scope of the presentinvention, and all such modifications as would be obvious to one skilledin the art are intended to be included within the scope of the followingclaims.
